  • Page 98: Installing Eproms

    Appendices 7. Installing EPROMs There are two EPROM sockets on top of the emulator. Evaluation involves executing the user application program directly from EPROMs in them. Emulation offers commands for transferring EPROM contents to code memory. Install an EPROM in its socket with the following procedure. (1) Turn off the power to the emulator.
  • Page 99 Appendices Pin 1 EPROM locking lever EPROM socket The sockets accept the following EPROM types. Note how the position of pin 1 differs for each type. • MSM27512 and compatible devices (64K 5 8 bits; 28 pins) • MSM27101 and compatible devices (128K 5 8 bits; 32 pins) (1) MSM27512 Pin 32 Install with pin 14 all the way to the right.
  • Page 100 Appendices _______________________________________________________________________________________________________________ n Note 1 n Always be sure that the power is off before removing or installing an EPROM. _______________________________________________________________________________________________________________________________ _______________________________________________________________________________________________________________ n Note 2 n A user application program always requires two EPROMs: one each in the EPROM.HIGH and EPROM.LOW sockets.

    If the Dr.63514 in-circuit emulator does not operate correctly even if above measures are taken, the Dr.63514 in-circuit emulator itself may have failed. Contact your Oki Electric Industry sales outlet or your Oki Electric Industry representative immediately.
